$2a^{2}(4a-b)(3a+2b)$
$24a^{4}+10a^{3}b-4a^{2}b^{2}$ 1. Factor the expression: $2a^{2}(12a^{2}+5ab-2b^{2})$ 2. Write as a sum or difference: $2a^{2}(12a^{2}+8ab-3ab-2b^{2})$ 3. Factor the expressions by taking out a 4a and -b: $2a^{2}(4a(3a+2b)-b((a+2b))$ 4. Factor the expression to get your answer: $2a^{2}(4a-b)(3a+2b)$
